[PATCH v2 0/2] TCPM non-pd mode

[Kyle Tso]

The reason for this patch is to let the device/system policy decide
whether PD is going to be supported using devicetree properties.

A new dt property "pd-supported" is introduced and TCPM uses this
property as a flag to decide whether PD is supported. If the flag is
false, the RX functionality of the low-level driver will not be enabled.
The power negotiation related states will be skipped as well. If the
flag is true, everything is as what it was before.

If "pd-supported" is not present, and the port is SRC or DRP, another
existing dt property "typec-power-opmode" needs to be specified to
indicate which Rp value should be used when the port is SRC.

changes since v1:
- revise the patch to use dt properties
